23_SMA-50-0-44/133_NE Equivalent & Substitute Parts

Part Overview

The 23_SMA-50-0-44/133_NE is an SMA Connector Jack with female socket configuration manufactured by Huber+Suhner, Inc. This coaxial RF connector is designed for 50 Ohm impedance applications with panel mount installation via solder cup termination. The connector operates across a frequency range up to 18 GHz and maintains active product status. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate component alternatives that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 23_SMA-50-0-44/133_NE are qualified based on strict equivalence across the following critical parameters:

Electrical Equivalence Criteria: Connector style (SMA), connector type (Jack, Female Socket), impedance (50 Ohms), contact termination (Solder Cup), shield termination (Solder), frequency maximum (18 GHz), center contact material (Beryllium Copper), and center contact plating (Gold) must be identical.

Mechanical Equivalence Criteria: Mounting type (Panel Mount), mounting feature (Flange), fastening type (Threaded), and number of ports (1) must match.

Performance Criteria: Mating cycles (500) must be equivalent or superior.

Both identified substitute parts—142-0701-636 from Cinch Connectivity Solutions Johnson and SF2950-6062 from Amphenol SV Microwave—satisfy all electrical and mechanical equivalence requirements. These parts are direct functional replacements suitable for identical circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—the primary 23_SMA-50-0-44/133_NE and the substitute parts 142-0701-636 and SF2950-6062—maintain active product status and are suitable for direct substitution in applications requiring SMA female jack connectors with 50 Ohm impedance and 18 GHz frequency capability.

142-0701-636 (Cinch Connectivity Solutions Johnson) carries RoHS3 compliance certification and REACH Affected status. This part supports an extended operating temperature range of -65°C to 165°C, exceeding the primary part specification. Moisture Sensitivity Level is rated as 1 (Unlimited).

SF2950-6062 (Amphenol SV Microwave) carries RoHS3 compliance certification and REACH Unaffected status, matching the regulatory profile of the primary part. This part is available in the highest inventory quantity (8800 pieces).

The primary part 23_SMA-50-0-44/133_NE carries REACH Unaffected status and maintains an operating temperature range of -65°C to 125°C. Selection between these parts should be based on inventory availability, regulatory requirements specific to the application, and operating temperature constraints.

Frequently Asked Questions (FAQ)

Q: Can 142-0701-636 be used as a direct replacement for 23_SMA-50-0-44/133_NE?

A: Yes. Both parts are electrically and mechanically equivalent SMA female jack connectors with 50 Ohm impedance, solder cup termination, panel mount configuration, and 18 GHz frequency capability. The primary difference is the extended operating temperature range of 142-0701-636 (-65°C to 165°C versus -65°C to 125°C) and its RoHS3 compliance status.

Q: Can SF2950-6062 be used as a direct replacement for 23_SMA-50-0-44/133_NE?

A: Yes. SF2950-6062 is electrically and mechanically equivalent to the primary part across all critical parameters including connector style, impedance, termination type, mounting configuration, and frequency range. Both parts share REACH Unaffected regulatory status.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by equivalence in connector style (SMA), connector type (female jack socket), impedance (50 Ohms), contact and shield termination methods (solder cup and solder), mounting type and feature (panel mount with flange), fastening type (threaded), frequency capability (18 GHz maximum), center contact material and plating (beryllium copper with gold plating), and mating cycle rating (500 cycles).

Q: Are there differences in body material between these parts?

A: Yes. The primary part 23_SMA-50-0-44/133_NE uses brass body with white bronze finish. The substitute 142-0701-636 uses brass body with nickel finish. The substitute SF2950-6062 uses stainless steel body. These material differences do not affect electrical or mechanical compatibility for standard RF applications.

Q: What is the significance of the operating temperature range differences?

A: The primary part operates from -65°C to 125°C. The substitute 142-0701-636 extends this range to -65°C to 165°C, providing capability for higher temperature applications. Selection should be based on the specific thermal requirements of the application.

Q: Do all three parts have the same mating cycle rating?

A: Yes. All three parts are rated for 500 mating cycles, indicating equivalent mechanical durability and connector longevity.

Q: What packaging format is used for these connectors?

A: All three parts are supplied in bulk packaging, suitable for direct integration into manufacturing processes without individual packaging.
